I have been lurking and reading and I wanted to chime in about the requirement to break down pico tanks regularly, that is not the only way. Im not saying that isn't a practice worth considering for many pico owners, it can help to reduce OTS and help your pico live longer especially if you have stocked with fish, but to make it a blanket statement for all small picos reflects limited experimentation with actual picos. I am not trying to hijack this thread, but I have a one gallon that hasn't been taken down in four years whatsoever, and my vid shows the necessary details this is just an example of how you can build a tank that does not ever have to be torn down. I am only writing this because if someone tells you something categorically can't be done, and you believe it, then nothing new progresses in the hobby. If you research responsibly you will find a way to do exactly what you want.
I didn't see miss debbie claim she had to break hers down over this first year or did I miss something?
Im not trying to flame so I will be specific.
I do weekly water changes in my tank, sometimes twice weekly. This is not cheating the longevity of the tank because I rate my tank maintenance in terms of minutes, and I spend less time per week on my picos than anyone does on their large tank, plus I don't have to topoff that removes comparative work as well. One can easily set up a 2.5 g with the internal refugium like I did and get the same effect. The mini scraper removes diatoms, so you don't have to tear it all down as posted, and a coathanger does all the rest for scraping coralline down low.
Detritus removal is the #1 thing that determines your tank's longevity. If you leave little pockets of it during service time, or if your tank is so packed you can't get to it is, then the frequent tear downs are helpful. If you can get it all, they are not required at all. Keeping fish really challenges the tank but is very possible as was posted earlier. For me, I just stock crabs and shrimp which are low bioload along with corals, and yes the live rock alone is enough to remove however many grams of waste are produced because again the video shows the detail of the tanks age.
The specifics of your feeding also matters as you get into multiple-years established picos. If you feed pelleted foods, the doughs and fillers used in them will be transported to your sandbed as little brown pockets of gunk over time, depending on your fauna but in the average pico this is a chief contributor to OTS. If you feed only cyclopeeze or frozen mysis, these natural feeds break down cleanly, before being transported into the sandbed, and you get a lot less nutrient sinking which again would require frequent breakdwn were it not for alternate planning. It is highly possible to keep very long term picos that are not plumbed so don't lose hope just get a lot of opinions, and take the ones with pics and videos very seriously lol
